ABSTRACT:
A transparent dome is mounted on a housing and extends from the top thereof. The housing has an oil reservoir, a source of electrical energy, an electric motor and a pump therein operated by the motor for pumping oil. A miniature oil drilling rig is mounted on the top of the housing in the dome and has a tube extending into the housing and into the oil reservoir whereby when adjustably positionable electrical contacts are moved into electrical contact with each other, the motor is energized by the source of electrical energy to operate the pump to continuously pump oil up through the pipe and out at the top of the rig. The oil returns to the reservoir via the dome and oil return slots in the top of the housing.
